With D-Link’s V-Click phone, you’ll be able to switch between “your tri-band 900/1800/1900MHz GSM/GPRS network or unspecified 802.11 WiFi to make low cost VoIP calls” at the push of a button. One caveat, you’ll have to shell out $600 for this baby. No word yet on availability.
The magic here is in that “v-click” button along the side which flips the WiFi radio. Once enabled, users can make SIP-based VoIP calls or hit the web over the bundled Opera Mobile browser and 176×220 pixel display
